AI-assisted summary
Description from the seller
Beautiful Grape Amethyst cluster (also known as Botryoidal Chalcedony), featuring natural rounded formations resembling a cluster of grapes.
The surface displays a soft lavender to violet hue with a delicate sparkle typical of high-quality specimens from Sulawesi, Indonesia.
This formation occurs when silica-rich fluids slowly crystallise in volcanic rock cavities, forming spherical, “bubble-like” crystal groups — a rare geological process that creates this organic, berry-like appearance.
Mounted on a decorative black metal stand, this piece serves as both a collector’s mineral specimen and a natural art object.
